I have a simple automation that notifies me if a contact sensor is left open for 5 minutes. Since one of the latest updates it'll notify me after 5 minutes even though the door was closed within the timeframe. I checked the door logs and it was closed within a matter of seconds yet the automation still notified me after 5 minutes.
I'm not aware of any specific mention of this issue, though it's possible it could be related to one of the known Rule trigger issues:
Either way, your rule in its entirety and the output from Logs with all logging enabled would be necessary to both demonstrate the problem and assist with troubleshooting if it's a Rule 5.1 problem.
